STUDY ON UNLOADING ROCK MASS CONSTITUTIVE RELATIONSHIP
The model experiment is applied to the geology material models, plaster cast models and sand syrup models. With analysis and fitting of the results got from model experiments, an initiatory increment constitutive relationship of jointed unloading rock masses is put forward. Fully considering the deficiency of the constitutive relationship, a new one is established with change on parameter choosing and physical meaning. Afterwards the constitutive relationship is put into ADINA, and an analysis is made for the high slope model of Geheyan hydropower station. By comparing the calculation results with those which were got by loading method, the rationality of the constitutive relationship is proved.
